What Is a Truck Driver’s Logbook?
A truck driver’s logbook, also known as a driver’s daily log, is a mandatory record of a commercial driver’s work and rest periods. It is a comprehensive record that tracks the driver’s duty status across a 24-hour period.
What Does a Logbook Track?
The logbook records a driver’s activities in four distinct categories, tracked in 15-minute increments:
- Off-duty: Time entirely free from work, including rest breaks.
- Sleeper berth: Rest inside a qualifying sleeper compartment.
- Driving: Time spent operating the vehicle.
- On-duty (not driving): Work-related tasks like loading, inspections, or paperwork.
Why Are Logbooks Required?
The Federal Motor Carrier Safety Administration (FMCSA) mandates logbooks to enforce Hours of Service (HOS) regulations, which limit driving hours to prevent driver fatigue. Fatigue is a factor in roughly 40% of all trucking accidents.
How Are Logbooks Kept?
Since 2017, the FMCSA has required most drivers to use Electronic Logging Devices (ELDs) that automatically record driving time. While paper logs are now primarily backups, the legal requirement to accurately record duty status remains unchanged.
Why Logbooks Matter After a Truck Accident
After a truck accident, the driver’s logbook becomes critical evidence. It can reveal whether the driver violated Hours of Service rules, exceeded driving limits, or falsified records all of which can establish negligence. An experienced truck accident attorney can subpoena these logs and work with experts to analyze them. Electronic logs are especially valuable because they are harder to alter than paper records. If a logbook shows the driver was fatigued or overworked at the time of the crash, it can significantly strengthen your claim for compensation.
